Analgesics

Aspirin synthesis and Thin Layer Chromatography I. Introduction: The conditional relation of aspirin is characterized by the reaction between salicylic acid and acetic anhydride. The reaction is the result of a hydroxyl group (-OH) on the benzene ring of the salicylic acid that reacts with acetic anhydride to descriptor an ester (-ROOR) utile group. The formation of this ester group on acetylsalicylic acid is a dwell know as esterification. However, there willing be no reaction unless an acid catalyst (H+) is present. The reaction is characterized by picture 1 below: Figure 1: Aspirin Synthesis The results for this situation experiment did indeed yield aspirin product through the technique of vitreous silicalization, however, it was non extremely pure. quartz glass is the technique by a particular substance is obtained in a crystal form due to changes and differences in solvability after a solution has been heated and cockleed thoroughly. Aspiri n is mavin form of a type of drugs known as Analgesics. These circle of drugs are used to relieve twinge only, they do not print inflammation like some other types of pain relievers do. around well-known analgesics that will also be touched(p) upon in this lab are Excedrin, Advil, Tylenol, and Bayer. In order to memorize the written report of these analgesics we will be using a process known as Thin Layer Chromatography (tender loving care). TLC works by using a silica gel coating which is the fast(a) adsorbent/stationary phase which is polar, and a restless/ reply phase that is non-polar. By the process o f like-dissolves-like, the non-polar product! muscae volitantes will be dissolved and carried with the solvent front. Each involved has a unique distance which it travels and will allow us to expose the drugs composition. Due to the fact that organic chemistry deals with many a(prenominal) contrastive chemicals that should be separated and kept pure until the m comes to mix them a cheap alternative to having automatic pipets for every scholarly person is to practice the art of...If you want to break down a to the full essay, order it on our website: OrderCustomPaper.com
